Product Description
Fire Sprinkler Steel Pipe is a specialized pipe designed for use in fire protection systems, particularly for wet, dry, pre-action, and deluge sprinkler systems. These pipes are engineered to withstand high pressure and deliver water or fire suppression agents reliably during emergencies.
Manufactured in compliance with ASTM A135, A795, A53, or BS 1387 standards, fire sprinkler steel pipes are commonly schedule 10 or 40, and are available in black or red painted finishes, as well as hot-dip galvanized for corrosion resistance.
They are widely used in commercial buildings, industrial facilities, warehouses, and residential high-rises, forming the main network of fire suppression systems.
